Question

take Pi equal to 22 / 7 find the radii of the circle whose areas are under and 314 2/7 mm²
​

Answer 1

Answer:radius =10 mm or 1 cm

Step-by-step explanation:

Area=314 2/7 mm²

=2200/7 mm²

Area=πr²

2200/7=22/7*r*r

100=r²

r=√100 mm²

r=10 mm

radius=1 cm

Answer 2

$area = 314\times \frac{2}{7 } \\ = \frac{2200}{7} mm^{2} \\ = area = \pi \: {r}^{2} \\ = \frac{2200}{7} = \frac{22}{7} \times r \times r \\ = r = \sqrt{100 \: mm^{2} } \\ = r = 10mm \\ = radius = 1cm \: ans \\ \\ i \: think \: helful \: for \: you .....$
